We can debate whether they're good things or not, but they clearly confound comparisons with non-charter schools, which do not get to apply those kinds of selection powers to improve their published outcomes.

I don't understand your comment at all, but I am very curious to know what you actually mean. Can you please clarify and expand? To begin, what do you mean by "they" when you say we can debate whether they're good things or not?
I'll try. People often say that students from charter schools outperform students from (other) public schools. If we let charter schools kick students out, we should let all public schools let kick students out so as to level the playing field.
Imagine we compare Denver Broncos against Miami Dolphins. Just a small adjustment. We require Miami Dolphins to let anyone who is a resident of Florida in the team. We put no such restriction on the Denver Broncos (because Go Broncos!) Now, we compare average 40 yard dash between the "average" Denver Broncos player and the "average" Miami Dolphins "player". What do you think will happen?
